Xliff | [Coke]: Can you install the libgdata package? | 03:17 | |
Also, what are the library names for libgio and libglib? | |||
I need the full names. | |||
Also need the name of your current version of the OS. | |||

tbrowder__ | hi, i have 2 hashes: %a{$k}{$id} = $unique-value and %b... of the same structure. | 11:30 | |
11:30
abraxxa joined
|
|||
tbrowder__ | i know i can merge them into %c with 2 loops, but i think a map is possible. can someone please show that? i haven't been able to wrap my mind around maps yet. | 11:33 | |
i meant to say merge them with, say, merging %b into %a | 11:35 | ||
one loop | |||
i can do that. | 11:36 | ||

kjp | tbrowder: You can't get away with something simpler like "my %c = Hash.new(%a.Slip, %b.Slip)", or do you need them merged at a lower level? | 12:09 | |
CIAvash | can't you just do: `my %c = %a, %b`? | 12:13 | |
lizmat | no, that won't merge the inner hashes | 12:15 | |
sadly, it looks like raku.land/cpan:TYIL/Hash::Merge also isn't the answer | 12:16 | ||
12:30
epony joined
|
|||
CIAvash | maybe something like `sub merge_hashes (%a, %b) { %a.map: { if .value ~~ Hash { |merge_hashes .value, %b{.key} } else { .key => %b{.key} // .value } } }` | 12:38 | |
tbrowder__ | ok, just one loop does fine, and much easier for me to visualize. and my real use case has to merge 4+ hashes, so only linear time O(total number of hash elements to add) | 12:41 | |
would be great for multicore | 12:42 | ||
but in truth hash sizes are small | 12:43 | ||
ab5tract | Xliff: you can also use `Terminal::Print::Input` ... it should probably have been it's own module | 12:44 | |
tellable6 | ab5tract, I'll pass your message to Xliff | ||
tbrowder__ | is there a raku module that could let me see a pdf doc rendered in a terminal? | 12:45 | |
that would be very cool | 12:46 | ||
ah, Terminal::Widgets has possibilities | 13:03 | ||
request submitted as an issue | 13:08 | ||

[Coke] | xliff: did 'brew install libgdata'. Do you need full names? I thought raku was smart about that. | 15:20 | |
tellable6 | [Coke], I'll pass your message to Xliff | ||
[Coke] | xliff: os is 14.1.2 which is "Sonoma", I think. | 15:21 | |

melezhik | o/ | 16:07 | |
any chance to speed up zef install ? | |||
zef install --/test github.com/melezhik/sparky.git takes a lot of time on a fresh box | 16:08 | ||
^^ ugexe | |||
even with disabled tests | |||
I know there are some "magic" flags for that )) | 16:09 | ||
actually the VM has several CPU cores if it helps for parallelization | |||
16:21

|
|||
jdv | that's more or less why i was asking about zef parallelization the other day | 16:33 | |
trying to install the deps for something ridiculous like blin takes a very long time | |||
[Coke] | to be fair, Sparky does have a lot of deps. | 17:38 | |
zef-deps Sparky | wc -l ;# 212 | 17:39 | ||
159 without whitespace lines, sorry | |||

|||
[Coke] | zef-deps Sparky | grep -v '^$' | sed -e 's/^ +//g' | sed -e 's/ ...//g' | sort -u | wc -l # 70 | 18:01 | |
^^ I wonder if I want a command line arg to zef-deps that gives us the list just after the sort. | |||

ugexe | the slowness is precompilation, which is outside of the control of the package manager | 21:57 | |
tellable6 | 2024-01-28T15:21:19Z #raku-dev <vrurg> ugexe There is a bit more to the parallelizing of module loading: gist.github.com/vrurg/37e9b23a29d2...034d79b8d1 | ||
ugexe | github.com/rakudo/rakudo/blob/d446...#L220-L230 | 21:58 | |
you can see here that you the actual "install" can only be done serially as well | |||
melezhik: is it any faster with github.com/rakudo/rakudo/pull/5425 ? you could also try adding a `:degree(...)` to the `$to-precompile.race(:batch(1)).map:` to however many cores you want it to use. it didn't end up speeding things up when i tried that PR, but theoretically it seems like it should improve precompilation on install time | 22:09 | ||
tellable6 | ugexe, I'll pass your message to melezhik | ||
22:10

|
|||
librasteve | so you can go something like zef install --no-precomp ? | 22:25 | |
just a thought that deferring precomp could speed up the install, moving the compilation to execution time (so would need --/test also) and thus may avoid compile of uncovered units and allow compiler parallelization during the run | 22:49 | ||

ugexe | yeah could be. i just wrote up github.com/ugexe/zef/issues/547 which has instructions for how to implement it in zef | 23:16 | |
which mostly involves passing a bool through various wrappers :) | |||
when running `zef install --/test` specifically though (i.e. install without testing) I think `RAKUDO_NO_PRECOMPILATION=1 zef install --/test ...` might work | 23:24 | ||
